Have you tried to change vga=0x31a to a value which is shown when you
enter scan on the prompt? If not, please, do so. And, please, enter
"scan" and not only press Enter.
Have you added nomodeset to the kernel line in /boot/grub/menu.lst? If
not, please, do so.
This has nothing to do with the nvidia and nouveau driver, because at
this time there are no modules loaded.
Please, add both kernel parameters vga= with a valid value and
nomodeset to the kernel line in /boot/grub/menu.lst.
This line has to look like this:
kernel /vmlinuz26 ... nomodeset ... vga=...

If you don't add the vga parameter to the kernel line you don't get a
framebuffer probably except if you are using KMS.
